Philippe Lamberts, co-leader of The Greens-European Free Alliance group said he “had his doubts” over the European Commission president, whose five-year term expires in 2019.

European Commission president Mr Juncker delivered his much-anticipated State of the Union speech on Wednesday with a swipe at Britain by insisting the EU will move towards greater integration despite Brexit.

Asked by Express.co.uk what he made of the speech, Mr Lamberts said: “Well, expected. Some bolder proposals, some transnationalism, some on the eurozone reform.

“But all-in-all, he proposes to stay the course. When I listen to that with the ears of many people who feel left behind by the current macroeconomic policies that we have, then I have my doubts because he still pushes for free trade deals that basically are tailor-made for multinationals.

“His Commission is still pushing for allowing poisons into our products like glyphosate and stuff like that.

“So you know, he’s a nice guy, he wishes well, but the thing is that the organisation that he presides is not delivering what he claims to be delivering and that is a big problem.”

Meanwhile, Hans-Olaf Henkel, vice-president of the European Parliament’s third-largest group the European Conservatives and Reformists, said Brexit was a “big disaster” that Mr Juncker was ignoring.

Speaking to Express.co.uk, Mr Henkel said the UK’s decision to leave the Brussels bloc would be just as bad for the EU as Britain.

He said: “He called it a full vision of Europe. I must say, it was more a fools vision of Europe because he seemed to have totally ignored the realities of Europe.

Mr Juncker set out his 12-month masterplan to steer the troubled bloc through the escalating refugee crisis and laid out plans to reform the eurozone.

Keen to push ahead with his masterplan, billed as the biggest reboot in the EU’s history, Mr Juncker ratcheted-up the federalisation of the 60-year-old bloc’s core economies.

It appears Jean-Claude Juncker is keen to make his mark in the European Union as his five-year term as European Commission president expires in 2019 with a grand ambition to rebuild the bloc, left in tatters after Britain’s momentous decision to leave.
